# NDI™

NDI command transmits video and audio captured by the device over NDI protocol.
Unlike other features, NDI does not output any data over TCP/UDP.
Video and audio are transmitted over NDI protocol, so you can receive the data with NDI client apps like NewTek NDI Video Monitor, TouchDesigner, etc.

The framerate follows the message rate in general settings.

NDI command is only available in ZIG SIM Pro.
Also, you cannot use NDI, ARKit and Image Detection simultaneously.

# Outputs

No outputs.

# Detail Settings

# Scene Type

• WORLD: everything captured by camera.
• HUMAN: human captured by camera.

※ HUMAN can be used on device equipped with A12 chip or higher.

# World Image Type

• CAMERA: send images captured by camera.
• DEPTH: send depth maps captured by camera.
• BOTH: send camera images in RGB channel and depth maps in alpha channel.

# Camera

Toggle camera between REAR and FRONT.

# Depth Type

• DEPTH: capture depth map.
• DISPARITY: capture disparity map.

# Human Image Type

• HUMAN: send human stencil images in RGB channel and alpha channel.
• BOTH1, BOTH2: send camera images in RGB channel and human stencil in alpha channel.

※The alpha in "HUMAN" for the front camera is depth map.
※The alpha in "BOTH1" is 0.5 .
※The alpha in "BOTH2" is a diff between alpha value and red value of the human part of images.

# Resolution

Choose the resolution of output images to send from the following:

• VGA: 640x480
• HD: 1280x720
• FHD: 1920x1080

# Audio

If ON, ZIG SIM will capture the audio from the microphone and send it over NDI protocol.

# Audio Latency

Choose the audio latency from LOW, MEDIUM and HIGH.
This setting changes the size of audio buffer used to store the audio data.

In LOW mode the latency of the received audio will be small, but may cause audio glitch.
In HIGH mode the audio will latency gets longer, but the quality will be more stable.
